+Fresh classic2–6 Basic/Advanced all14 may now select independent36 plus
+original Nexus12 without any other overlay. One public configuration
+predicate joins the original initializers and effect quotes; native offers,
+starting-card-before-training order and mandatory normal Banker remain.
+An unused expansion selection is not part of this entry. Native selected
+families, World/phase/Discovery/Semuta and reaction-preview envelopes retain
+their existing separate limits; no played save is converted.
+
+Actual normal module selection completes original training and first Storm.
+Real Nexus draws then exercise Recruits/fixed Tleilaxu revival, a selected
+ordinary bank purchase and native Cunning with separate Reinforcements fees
+and Harass returns. Frozen25-file249/249, types/lint/build, three390px
+surfaces and four legal all14 policies pass. Broader effect bounds, full
+combinations, strategy, deferred assurance and deployed acceptance stay open.
